Water vapour permeation through clear coatings

Analytical expressions are derived, and three distinct regimes are evidenced: i/ a thin membrane – low current domain, where all reduced protons enter into the metal and

Figure 17: Permeation transients measured for steel A membranes of different thickness, exposed to test solution at pH 5.5 saturated with 100 mbar H 2 S and 900 mbar CO 2. Figure

- above the critical thickness, in a thick membrane situation, the sub-surface concentration is constant and the diffusion flux is inversely proportional with the thickness...

Ces anomalies (exprimées en %) sont indiquées dans le Tableau 9. A partir des anomalies mensuelles générées par les modèles ARP et MPI, nous avons pu déterminer une chronique

rod (cold rolled steel) threaded full length were used as extensions above ground for positioning the reaction frames over each pile. Table 3 gives the depth to

Section 6.2 presents the experimental results for a buck converter having an adaptive coupled-magnetic output filter (as detailed in Chapter 3), while Section 6.3

Spreading/permeation mechanism of an EPC vesicle on striped patterns (2.5 µm width) as a function of time (from left to right): (1) regime I, approach; (2 and 3) regime II, spreading

There exist direct evidence that the reaction H 0.5 → H 0.6 actually takes place in the AB interval : the inflection point of the isotherm (i.e. the point of maximum slope
